Threads used on husqvarna 2 strokes?

[julianf]

Ive got one of these -

Mine is WAY less shiny though!

The fasteners on the recoil unit are mostly missing. The two that remain are different threads, which im sure is a prior bodge. (so i cant even measure one, as im not sure which is the correct one)

All i can find is husqvarna part numbers, and retailers charging a quid fifty a screw (plus £3.50 post!).

This is a pattern cover, with the screws -

Id imagine the thread is the same used on all husqvarna 2 strokes - anyone got any idea what that is?

Thank you.

If one's already been bodged, I'd be tempted to helicoil them, then they can be whatever thread you want.

Sure, that would be a good plan, but it may be that there is not much meat around the threads. I think it would be preferable to try and get the correct fasteners first.

There are a number of fixing points. I dont even need them all to be good.

can't you just drill and tap the holes a bit bigger ?

I think the 11 in the number is the length of the unthreaded portion
