Tecumseh engine issue
I recently bought a rotavator, it has a Tecumseh Prisma 37 engine. When it came all of the linkages on the throttle were in the wrong place so i changed them according to diagrams on the internet.
The problem i have now is that the engine will not rev at a reasonable speed. Its revs very high and if you close the throttle slightly the revs fall sharply and it stalls. The opposite for increasing the throttle, it rises very quickly to a very high rate.
I have adjusted the limiting screws and seemed to have tried many different set ups all with the same result.
Has anybody else had this problem or does anybody know how to fix it?
