The problem started out a year ago with occasional "stumbling." I thought it was water or ethanol causing a fuel problem. Then driving down the road one day, a loud backfire and no start. Amazingly it started after it sat for a while.....ran then quit and wouldn't start. Someone suggested dirt in the Carb.
I took it to a local dealer who said it was the CDI. He reported no spark initially. He also verified magneto magnets are intact and working correctly. He got it running with his new CDI, I found a so called new CDI on ebay. It started successfully after a few attempts and ran for awhile. Now I'm back to the same old problem...wont start.
Either there is a secondary underlying problem here or my replacement CDI is also defective. I would like to verify these CDIs. Are they ever intermittent? ....or do they work or not work.
I dont accept that these CDI's cant be tested. Someone manufactured them, Cat put them on their machines, someone has to stand behind them. Cat should stand by them if no one else can. Cat is too hard to get a hold of.
My next plan is to take it back to the Dealer and see if he can start it with his CDI, if so then swap my CDI and see if it works also. Not sure how I can negotiate this with him.
