Clutch spring hack

Did the reset and put it away. I'll find out how well it runs the next time I pull it up a tree (hopefully never).

OK. Yes. That's a shit plan. I better go and cut something with it. Back to you in due course.

You really need to check for air leaks as holding onto a high idle is a good sign that something isn't right. Unless you have a few tools to block off the carb, exhaust and have a pressure tester you need to at least check manifold pipes, impulse pipes and check all fuel lines.

If it is till doing it get it pressure tested as its a good few quid to replace a piston and cylinder.

I was going to drop it to a shop to read the ECU, pressure test etc but timing (scheduling) didn't work. It's the saw I put a new fuel tank on when a branch got dropped on it. Quite conceivable that other damage happened at the same time so I've been reading the plug fairly regularly. Always fine but the running on did worry me for reasons you allude to.

As a sort of quick leak test I use brake cleaner fitted with a d40 smart straw (this thing

All the benefits of the original WD-40 formula, but with a Smart Straw for precision application. Simply flip the straw up for a narrow stream or fold it down for a regular wide spray...

and spray it around the intake boot impulse pipe area. You only need to spray a little, if there is a leak the engine will die. You have to make sure none of the spray is going into the carb, although with a little care you can use it to detect carb leaks. The wd40 will probably act the same as brake cleaner but I use a lot of brake cleaner and I fit them with that straw. 

 

Hmmm, maybe I should make some arb saw cleaner, smart straw plus brake cleaner. Yours for only £75.95 a can. Or buy two for £151.90

Bargain.
