Hi no belt, I will take a picture when I go over the allotment later today, the clutch operates some thing inside of the gearbox, I have tried to find a parts manual without success.
I have a Honda F260 rotavator 2 speed gearbox, sometimes the tines stop rotating if they hit hard soil but the engine does not alter in speed, what is the design of the clutch and what might be the problem.
I decided to phone a rebore company of 35 years experience in high performance motor bike engines and I can see them tomorrow, they are prepared to check the engine over including measurements while I wait, I may have something to report back tomorrow.
Curiosity got the better of me I couldn’t wait until the winter, now stripped the engine down and could find only one possible problem causing excessive oil consumption, it used 300ml in 2/3 hours use, and the oil ring gap was only about 20 degree away from the middle ring gap and should have been 120 degree a third apart, do you thing the close proximity could be the problem?
The manual quotes a maximum of .027 ring gap I have less than .015 on all the new rings.
All other measurements are within manual specifications.
Thanks for your reply I didnt get back sooner been away at a steam rally only just got home.
I did used a new set of ring from Cox & Turner with the scraper ring being a one piece as apposed to the three split type I thought they were gapped correctly but I am now thinking that is where my problem is.
This weekend I had to top up the oil by 300 ml didnt smoke much only on start up, comlete strip down now, and start again.
Looks like a fuel stabiliser is a good idea for small engines, £7 for about 300 Ltr treatment is not bad and should help prevent ethanol clogging of the carburettor.
Yes that was me at times, I still need rings but I found out yesterday that was not the only problem for the smoke.
First my stationary engine packed up then on Sunday did the WH then yesterday did my 30 year old Escort car all with smoke problems (I mean a lot ), I had used petrol from a 20Ltr jerry can which was about 6 months old I checked it and yes it was contaminated, now having to drain the car tank and other machines.
Is any one going to Wiston this year 2018 I have an entry form to enter my two WH and would like to add to a section if possible,, I will be tied up in the working section with another display.
