    At the beginning of the season I bought 3 br600's and 1 br420. The 600's were all in parts and were from a commercial company downsizing and these were their parts blowers but I figures out of 3 I could most likely get 2 running. When I got them after messing with them for a while I got two of them to start but they had the wrong spark plugs in them so after 20 minutes they died. I took them back into the garage and not realizing it was the spark plug I was messing round with the ignition coil, fly wheel etc. and couldnt get anything later I figured it must be the plug so I put the right plug in and it still wouldnt start. Noticing the spark was not very large I replaced the fly wheel and put a used coil on but in much better shape. After trying that I still can not get it to run. I cleaned the carb and air filter etc. I am out of ideas. Does anyone have anything I can try or heard of this before? There is a little bit bigger spark with the new fly wheel but not much? The compression is not great but they are not horrible... any thoughts would be appreciated, Thank you Joe

    I would put those 600 on the back burner and concentrate on the 2 stoke BR420. That unit is a lot easier to work on and worth putting a few bucks in to get it running. I wouldn't even mess with those 4 mix tooo many complicated things that could be a problem. Sell them for parts.

    should be in owners manual, i've never done it on a blower but from what i've read here they do require it periodically. i have had to do it on several dirtbikes and they are extremely difficult to start, if at all when the valves get out of spec

    i suppose it is possible that if they were too far out of spec that it could be a cause of lower compression if one isn't closing all the way. it's hard to say without knowing the motor
