Hello,

I have been trying to bring to life a Honda CV160 on a tiller. I have replaced the carb with a new(cause I broke off the choke knob 😱), I also cleaned the fuel tank, and replaced the vacuum gas fuel pump ad filter. It has been backfiring through the carb and air filter. I used starting fluid during diagnosis and had a very nice Fire going on!

I pulled the shroud off, cleaned the magnets on the fly wheel. I used a business card to check the air gap, it fine. I then pulled the valve cover off and checked the pulley alignment tabs. I was at TDC, the valves were both closed, the timing belt was intact. The mag out good spark.

Here is what I don't understand. When the pulley marks are parrel wit the case of the engine and the piston is TDC, the magnets on the flywheel seems to have just cleared the coil pickups. Should the magnets be UNDER the coil?

If no good, it is heading to the junk pile.

P.S. When I changed the oil in it, it was very "watery" like it was contaminated with gas.

Help please!

Thanks

WWoW

  If the key is OK I think you have an intake valve not closing completely.

As posted earlier, check the fly key. If no issues there, run a comp test. Also a visual inspection of the rockers wouldn't hurt. I worked on one, and had the same issues you described, and found one of the rockers had a crack in it allowing it to flex. This in turn didn't allow the valve to open completely. Later I found out these are notorious for rocker arm issues! They use cheap, thin, stampped material to make them. Good thing is, if you have to replace one or both, they are super cheap. Good luck, cheers;)
