Support your local machine shop

As a factory, we cannot sell retail. We sell to warehouses, then they sell to retailers. There are very competitive prices online. However, there is priceless value of a good relationship with a reputable machine shop / engine builder. You could take a day and visit the shops in neighboring towns, counties, even the next big city. See what they’re working on, what they’re capable of doing, and if they retail parts. They likely already order parts from a warehouse that stocks Elgin, ask them if they can be competitive with the pricing of a couple part numbers. A little bit of mark-up compared to online, can be well worth the trade-off for free knowledge from a seasoned engine builder. If you do choose to buy online, it’s best to find a retailer that offers excellent customer service and supports the Elgin product line, they can also help you with other parts and complete kits.

Build your knowledge

If you have engine building experience or have advanced technical questions, we strongly recommend joining the AERA Engine Builders Association. Since 1922, they continue to be an excellent resource for engine building processes, specifications, failure analysis, and data for all platforms of engines. Today on their website they offer  online machining and engine building certifications as well as automotive grants and scholarships.
