Hi have an issue with fuel leakage from cap!
Thought need a new cap! but got the 372 up and swapped caps over not leaking on 372 but is still on 346 wtf will have another look later and see if can clean anything that is stuck around hole i did clean seal  and area but won't hurt to do again before i boot it out of window!!!
 
On another note how do you tell if a 45cc or 50cc? mine don't have a decompression button or fuel blob running. 325/058 and how much compression would you feel turning it over by hand ? don't feel massive for sure but it does run well once fired up and cuts well even with rakers skimmed down a fair bit

Check threads are good and inspect fpr cracks around opening

Hi can't see any cracks what i might do later is wipe round with some lighter fuel then colour it with black felt tip then wipe of so should see if cracks as gets into crack! but it seems to get past seal/ring round cap

Orange top cover clips, no primer, 45cc

 

Grey clips, primer, 50cc

 

Some of the NE 346 50cc did come with orange clutch covers too. So not a 100% sure fire tell tell.  One dealer that sent me this one had like 5 come in with orange covers.

That is the piston dia ( 41.79 or something like that ) for the smaller 45cc engine  and 44,3 is the piston dia for the 50cc one .

Mmm dunno about that . Would have to measure the pitch of the pot mounting holes ( not sure if it used the old cank cases and the bigger saw might be a different stroke  )  ADW might know for sure . @adw

The 50cc goes on the 45cc body, straight fit. Some will tell you the 50cc one needs the primer but I have done a couple and they work fine with no primer system as long as the machine is set up correctly.

Yes it can be done, the bolt spacing on the crankcase base did not change, nor did the stroke, expensive to do if you fit a genuine cylinder assembly.

I was gonna say about that but thought it might get messy .  Also there was the one with , I think orange clips , orange side cover but with an auto de comp and being 50cc .  I had one . Took the pipe off , crimped the connector and fitted a blue, no it was grey decomp . 

Never an auto deco valve on 346 Stubby, that disaster was on the 357 and the 335/338xpt, strangely enough it worked well on the top hadle saw, you are right the oil cap is a different size, I just thought it worth saying you can fit the flip up cap on the fuel tank, I have done it on many 300 series saws.
