That darned ole JD V50 HELP KEVIN!!!

[AtLast]

I rebuilt the ole JD V50...but not quite sure how to " tweek" her up....doesnt seem to have quit the UMPH that I think it should....any suggestions?????

[jimc]

Is this the older yellow 50V (Echo)? I still have one I bought new.
What did you do to rebuild? Does this saw have the stock points ignition?
Suggest starting off checking the basics - compression,  case leaks, gas filter, plug color, etc. Maybe it just needs break in time.

[Kevin]

Did you get the carb adjusted properly?
What rpm are you getting?

[AtLast]

Kevin..I cant answer either question..all I can tell you is that I went with the factory settings on the carb....It runs " good"...just not " strong"

ji mc.....yes its the yellow saw...sat in my neighbors garage for a few years  till 1 day he brought it down and gave it to me....I put a new carb on it because they didnt have a rebuild kit for that particular saw....I have not done anything other than cleaned it up...new fuel filter and fuel lines

[Kevin]

There are a few things at the carb that could cause this including air leaks, a chain that's too tight will do this as well.
Plugged air filter.

Kevin....I checked carb seal  and tried to adjust carb levels but now its even worse  :-/....the 2 adjustments for high and low smoothed out but constantly bogs  and wont run full throttle.....HELP!!!

[Kevin]

Hows the chain brake, could be dragging?
Exhaust port and muffler clean?
Did you do a compression test?

[AtLast]

Kevin,
There is no chain brake....
Muffler is good..no compression check other than the ole fashioned way....like I said...when it runs its runs good....as soon as you put a load to it she bogs...

[Tom]

coming out of right field....... :D

I had a two stroke bike that did that after a top-end rebuild and i found that the rings (it had two)  were lined up.

Sure sounds like a compresion problem.

Mine needed the fuel pickup hose replaced a couple of years ago - make sure yours hasn't turned to mush and is choking off fuel supply under a load.
Same goes for the pickup filter - you can blow it out when you check the hose .

Kevin.....well...as it turned out the re is a VERY little  spacer that goes between the carb body and the choke body...that " grommet" was missing and not allowing the carb to seat properly....once replace and tuned up by a pro it runs like a Deere...fantastic saw..OMG this thing is soo strong.....thanks for all the help!!!!!!!!

[Kevin]

Sounds like a cheap fix.
Good going.
