The grass box to this mower required a bit of work to make it fit this machine. It was from a later machine and had different brackets. Here is a photo after the modification and test fitting.
Finally got to the bottom of the non starting problem....... A mixture of a slightly moved flywheel and a poor seal on the crankcase drain plug. All is fixed now and running really well. Will get a video tomorrow, but for the meantime a front and rear photo.......
Cheers Richard! 1....... What are you doing up at 3am? 2....... Whatever your on, I want some!!!lol
In answer to your postcard...... I have tried fuel straight in the plug hole, checked the crank case (engine was completely stripped and rebuilt) I made all new gaskets and used RTV gasket sealant to ensure an air tight crankcase and good seal to the barrel. The crank has no play/leaks in the bronze bushings, so compression is good. It also has good draw on air/fuel from the carb. I did rest the plug on cooling fins or bare metal to test spark, spark is regular, bright and strong so doubt its lost under compression.
My Dad used to work a lot on Villiers engines on old bikes, he seems to think its fuel related as the plug isn't very wet? There is fuel mixture getting through, some was present when checking crank drain plug. So thats where Im gonna start today, pull the carb apart and start from scratch! I have my 14" to compare with, It uses the same engine and runs a dream, so will set this engine the same and see what happens???
It should have stayed there too! Driven me nuts today. When I rebuilt the engine I fitted a new coil, it had a good strong spark when I put it away before painting all the green bits. Finished putting the mower back together earlier and tried to start it...... nothing! No cough, no splutter, dead! Checked for fuel, yep! Checked for spark..... erm? no spark? Retimed the engine and flywheel, still no spark. Cleaned and regapped the points and spark now returned! So you would think it would run? No...... dead as a dodo! Have taken the carb apart, cleaned it and reassembled.....Gave up for today, Its far too hot to be thinking!!!
Refitted the cylinder and bottom blade yesterday, adjusted them, and did the 'shiny paper' test......... nice pile of confetti! Then put the rest of the machine back together, but it got too late to start it up, A job for today maybe?
Thanks Ian....... Couldn't resist starting to put it back together! Managed to get this far yesterday....... the cylinder and bottom blade are being dropped off at a mates for grinding. He works at a golf course and will be doing it over his lunch break.
Have managed to make a good bit of progress in the last couple of days. The rollers have been filled, removing the very deepest pitting, etch primed and painted silver. Also refitted the flywheel cover and secured using new brass screws.
These 2 pictures bring us up to date....... Yesterday I welded 15 cracks in the cylinder blades, Vee'd them, drilled a small hole at the end on the crack to prevent it from running, and then welded the crack and hole both sides and smoothed out with the flap disk. Here it is with todays progress, the 1st bit of colour........ Also painted the clutch mechanism and the flywheel cover......
All the Aluminium parts have been cleaned as have all the nuts and bolt. Threads cleaned, some fittings replaced. The carb has has the once over and required the housing to be 'heli-coiled' as it had stripped the thread for the banjo bolt.
I had a duff coil and purchased an almost new replacement. Fitted, and pleased to report a good strong spark. The engine is all ready to go back on the mower. Exhaust has been painted with VHT paint.
As promised some pictures of this mower. Unfortunately I don't have any prior to starting this project as my phone has done the android 5.0 update, has had an episode and deleted all the pictures I had......... If anyone from Ardingly has any of this mower next to my restored 14" Atco, I would very much appreciate a copy???
So, here is where we are......... The mower was missing a grass box, one was sourced from the bay of E, not in too bad a condition, a few dents but nothing that cant be fixed.
These are the larger parts back from the blasters. The rollers will require a small amount of metal filler to improve some of the deep pitting...... the rest is all in etch primer ready for paint.
A quick question guys...... Does anyone have a photo of my 14" Atco, with the unrestored 12" Kev and I 'shared' next to it???? Flippin phone has had a meltdown and deleted most of the pictures on it!!!!
Cheers Paul and Gareth, have managed to source a fairly new, tested and working coil from George at Villiersparts for sensible money. He has no new in stock at the mo, and apparently neither has anyone else! At least another month before brand new ones are available again!
Hi! You all seem to be having fun at the rallies........The weather seems kinder this year! I hope someone is able to refresh my memory on how to test a coil on the little Atco Villiers 79cc engine??? I seem to be having a senior moment and have totally forgotten! This is for the engine I had as a spare. I'm fitting it to the little 12" Atco I accquired at Ardingly, which Kev and I shared. Have managed to source a grass box for it, and have gotten a new ignition lead. The rest is stripped and currently at the blasters. So the engine is getting a makeover and currently has no spark!
Edit! Here's a picture Before it was separated from its engine, its all I have as my phone has been randomly deleting photo's???
Just to add, its fixed and running sweetly again! Unblocked the fuel cap breather with the airline, cleaned the carb and tank, added some fresh fuel and away it went. However, the locknut for the carb adjustment seems to be missing and it winds itself back in with the vibrations. Temp fix is an 'R' pin, until I collect a locknut.....
Hi, I know its not old, but a good friend who owns this tractor has asked if I could replace the rotten deck? They have a fishery in Oxfordshire and use the mower regular for keeping the paths and estate kept. Im after a good replacement deck, preferably no rust, or a complete donor machine complete with solid deck. Failing that, is there anyone who knows if these can be purchased new???
Thanks! But Im starting to dislike these little engines.
I wish they would just run..... Spent a large part of the day trying to get them to do more than cough and splutter. Have fuel, have spark, both are getting fuel to the plug...... But they just wont start!
The Ohlsson Rice 3/4hp I have is almost as bad. It has had a complete rebuild, new barrel, piston, carb, coil, full set of seals and gaskets. More TLC than I care to remember, countless evenings where I've given up..... It too has spark and fuel, it starts, runs for 20-30 seconds then stops. No matter where I set the mix, its the same.
Expensive and Unusual paperweights spring to mind!!!
