Thank you very much for information.
The problem is a little different.
I have a mower Snapper ELT 1838 RDF.
When mowing grass clog discharge.
I wonted to try to increase top speed from 2700 rpm to 3000 rpm to improve the ejection of grass.
I have a tachometer and tang bender, but I don't now, what to bend.
Sorry for my english.
