Hi The issue with grinding to clear is that if the nuts are moved you may have to repeat the operation. It looks like the Draganfly washers are standard design, better to source some thin ones, and if that doesn't give the required clearance cross drill the bolts and fit castellated as per design. S...

Hi Simon

From memory there is a thin steel washer, (C 0.012"), under each nut - know anyone with a mill who could cross drill the bolts for you?

Regards Mick

Hi Simon I've attached a snag from a disassembly photo, it's the best I have of the nut, may give you some indication of where to concentrate: Big End Nut.png Regards Mick Edit: Just looking on the Draganfly website I see there are two types of nut, are you using the self locking ones, the castelatt...

Hi Simon Have you shimmed the crank to set the end float yet? Why not just compare the old and new components and see where the discrepancy is? Is the contact the result of big end movement not being restricted by the pistons in the bores? I used the original bolts etc. as they are positively locked...

Hi Simon

Difficult to be sure:
I think I'd be tempted to adjust' the strainer with a grind stone in a Dremel rather than try to bend the tube, (and especially not in situ).

Regards Mick

Hi Simon Here's a couple of photos of mine, which is used in conjunction with an original strainer: Sump Pick Up.png Sump Pick Up 2.png and a rather poor photo of another original strainer, (believed to be one removed from an A10). Sump Strainer.png Hope they are good enough for you to compare and i...

Hi If you are getting a couple of bangs and then nothing it sounds like it's fuel limiting. Go with what you're doing and try increasing the throttle opening, (I use about 1/8th), or increase the tickle time, (you are tickling until fuel is evident at the tickler aren't you?). If it fires with an 1/...

Hi I'd suggest doing your 'priming' kicks before you tickle the carb, you may be expelling all the rich, (tickled), fuel during your priming. I don't use the air slide at all until the engine fires, then I adjust to a point where the engine is happy to self sustain without blipping the throttle, the...

Hi You can, but it could be pretty precarious depending on how large the table lift is. Best to make some wooden frame tube cradles so as to support the frame clear of the prop stand lug, exhaust etc. and ensure it goes up perpendicular. Personally, if I didn't have a bike lift I'd do it on the cent...

Hi I was wondering what could have caused a failure such as this and I think you have the answer in the, non standard, cylinder base gasket. In my opinion, leather will compress in use due to the heat cycling of the engine and the barrel nuts will lose torque. Unless you are going to engage in a str...
