I am very impressed with that Bolens. All mine are Tube Frames virtually. I do like the look of the style of the QTs. The Q denotes Quiet apparently and that certainly appears to be the case with yours. You got me thinking.....
Did you make the point links?
Norman's right about the Leylandii. I got some from a customer last January (2015) and there is still a bit if sap seeping through. Gives out a good heat though so worth storing it for a couple of seasons.
I know that the Kohler twin engines in the Bolens Large Frames (1886 models) have a tendency to overheat but whether that is the design of the engine or the lack of air glow within the engine bay I am not too certain. One thing for sure if the engine is shot it will be very expensive to repair.
Get in touch with Rick aka Blackjakexxxxvvx on GTT. He's a top bloke and may be able to help you out. You could mention my name Andrew from the UK.
Enjoy Florida!
Brilliant find and a rare one to boot too!
I will ill be really interested to see more photos of this. For more info, get some photos up on GTT in the appropriate forum.
That's my understanding too.
The only other thing is to dig deep and try and get the parts from the US from a supplier who might be breaking a HT20/ implement.
