Gunna need to try 1 of these chips 1 day. My 81 still has a bit of a sad spark to it. Runs OK but does have a clear "miss" to it when first started and will just cut if left to idle while it's cold.
Went away after cleaning up the points but sorta back again.
My victa 2 stroke lawn mowers of a certain vintage in the 80s early 90s ran a chip just like these. Actually often a victa with no spark is the chip. Later on they built them into the coil anyway bla bla I'm pickin I could probably use 1 on a saw
Orr... I tear apart the 850 and flog it's engine
mint 850 but it won't oil to save its life and is heavy compared to the 81.
I actually rather run my ducted exhaust 800 over the 850. I'm convinced the 800 pulls a higher RPM. 850 fends off a stall slightly better but that 800 man that 800 howls
Maybe it's this great big hole
The 850 oiler....
I've tried a new pump I had I know pumps. No change.
I've stuffed a ground down nut under the pump incase it was the seal. Nup
It oils at idle happily.
Open throttle it goes dry and when manually pumping it needs re primed.
Eg 3 or 4 pumps before pushing oil. 5 seconds later same thing.
Grrrr so parked it is awaiting something or nothing I dunno it's just parked. I use a Poulan or husky instead hopefully pissing it off enough to make it realise it's missing out
Hopefully also it reads this too
