Hi all 2 strokers,

I will say that these small 2 stroke motors are not my specialty and thus I am asking for help.

I was given a Pro Mac II brushcutter and wanted to get it up and running as it's a fairly solid straight shaft machine and I'd prefer to use one of those opposed to a bent shaft domestic unit.

I worked it out that it was the coil that was at fault and thus this pretty much renders these machines useless, so I put it aside and waited for another similar machine with the same power plant to be listed on Gumtree.

Well I found one with a bent shaft that wasn't working properly but had a working coil and with that I felt I could make one machine out of the two.

I got the replacement machine to start but as soon as I put any pressure on the throttle it would stall. I ran a carby kit through it and it's still the same, only that it starts much more easily now with a single pull but it still stalls at the slightest pressure on the trigger.

BTW I took the Walbro carb from the original machine and rebuilt that and placed it on the second engine acquired that had a Zama carby on it but nearly identical, regardless it does the same with both carby's which tells me it's something else.

Any clues ?


Cheers,
BB.
