Good to see this info - I am having trouble with a diff engine builder I chose about a year ago - yes one year ago!!! I paid the guy upfront and he ran into financial problems and I have paid the ultimate price. No motor YET and out the money. Supposedly he is still working to make the deal right......long story that I previously posted in the Scammer section.
Motor is suppose to come soon- HOWEVER IF NEED BE AND I HAVE TO SELECT A NEW BUILDER WITH 100% CERTAINTY I WILL NOT BUY FROM DYNOFLO after reading the history and more importantly the responses from the owner.
Local builders will always work out best IMO.
